overview of Ceramic Fiber Blanket
Ceramic fiber blanket is a kind of continuous cotton flat fiber blanket made of high-purity raw materials, which is formed by high-temperature melting, spinning, and needle punching. It is a pure inorganic fiber material, which can be divided into ordinary type (1100°C), standard type (1260°C), high-temperature type (1400°C), and ultra-high temperature type (1600°C) according to the classification temperature.
technical specification of Ceramic Fiber Blanket
Ceramic fiber blankets are a common type of insulation material. The technical parameters of this material mainly include the following aspects:
1. Operating Temperature
Different types of ceramic fiber blankets have different operating temperature ranges. For instance, the 1260 ceramic fiber blanket has an operating temperature of 1100℃, which can meet various high-temperature usage environments; while the ceramic fiber strip with a short-term operating temperature of up to 1260℃ and a continuous operating temperature of up to 1000℃; and there is also the fire-resistant ceramic fiber blanket, with a heat resistance temperature of up to 1600℃ and a fire resistance temperature even up to 1800℃.
2. Thermal Conductivity
Thermal conductivity is an important indicator for evaluating the insulation performance of materials. The thermal conductivity of 1260 ceramic fiber blanket at different temperatures is as follows: 0.09 W/mK (400℃), 0.176 W/mK (800℃), 0.22 W/mK (1000℃); the thermal conductivity of 1260 fiber blanket is 0.08 W/mK; the thermal conductivity of fire-resistant ceramic fiber blanket is 0.05 W/mK.
3. Tensile Strength
Tensile strength reflects the mechanical properties of the material. The tensile strength of 1260 ceramic fiber blanket is ≥ 21 MPa, which can ensure that the product is not easily damaged; the tensile strength of the refractory ceramic fiber blanket is 0.3 MPa.
4. Dimensions
The dimensions of the ceramic fiber blanket can be customized according to the usage requirements. For instance, the dimensions of the 1260 ceramic fiber blanket are 3600x610x10-50mm; the external dimensions of the ceramic fiber blanket module are 7200x610x10-50mm.
5. Other Parameters
Density: The fiber density of the 1260 fiber blanket is 2600 Kg/m³; the 1400 fiber cotton blanket has a fiber density of 2800 Kg/m³; the 1500 fiber blanket has a fiber density of 3100 Kg/m³.
Linear shrinkage: Ceramic fiber blankets have the advantage of low heat shrinkage.
Chemical stability: Ceramic fiber blankets have good resistance to acid and alkali corrosion and the ability to resist erosion by molten metals such as aluminum and zinc.
These are some of the main technical parameters of ceramic fiber blankets. These parameters determine their applicability and performance in different application scenarios.
features of Ceramic Fiber Blanket
Ceramic fiber blankets are a type of insulation material with multiple excellent properties. Their characteristics can be summarized from the following aspects.
High-temperature resistance:
The main components are alumina, silica, etc. The classification temperature ranges from 1050-1500℃. It can remain stable in high-temperature environments, does not melt or burn, and is an A-class non-combustible material. Good heat insulation effect:
The thermal conductivity is low, generally ranging from 0.03-0.12W/(m·K), which is more than 50% lower than that of traditional refractory bricks. It can effectively reduce heat transfer, reduce heat loss, and save energy. Light weight:
The density is only 96-256kg/m³, which is 1/5-1/10 of traditional refractory materials. It can reduce the weight of equipment, lower the load of kiln structures and foundations.
Good flexibility:
It is a non-crystalline material with good toughness and elasticity. It is easy to cut and bend, and can be processed into various shapes as needed, making installation and construction convenient.
Excellent thermal shock stability:
It can withstand sudden temperature changes, such as 1000℃ to room temperature repeated cycles, and is not prone to cracking due to thermal stress. It has a long service life.
Excellent sound absorption and noise reduction performance:
Its multi-fiber structure gives it good sound absorption and noise reduction capabilities. When sound waves pass through, they are reflected, superimposed, and collided by countless fibers, converting energy into heat, thereby reducing the intensity of the sound waves. Good chemical stability:
It is not prone to react with common chemical substances and can maintain stable performance in various harsh environments. It has strong corrosion resistance and oxidation resistance.
High dimensional stability:
Produced by special processes, the fibers are evenly distributed, with small dimensional errors and good flatness. It can maintain good stability in both high-temperature and low-temperature conditions.
